I am so sorry to hear this!! I wish I were there so I could help you look! I have never had a cat, but I know if my dog was missing I would totally freak out! It IS like your baby, I totally understand.
I'm so not surprised that your stomach is reacting to the stress, I think most of us can relate! Having to run to the potty in between searches that many times sounds awful, you must just be having such a rotten time of it!
Let us know if you find your kitty! I'll be sending good thoughts your way!
**hugs** --Steph
